Abstract: An organizer freely designates a purpose, forms a community, very easily and efficiently collects money from participants, and gives a gift. To accomplish this, a community gift system that, when giving a gift to a specified recipient, allows an organizer and participants to form a community and collect money in the community as a cost of gift giving, includes a generator that generates a community database including name data of the organizer and data of the recipient in response to access via a network from the organizer who plans the gift giving, and a storage unit that accepts payment of money via the network from a participant who has approved of the gift giving, and stores data of the paid money in the community database so that the money can be used as the cost of the gift giving.

Abstract: An integrated transmission apparatus includes a plurality of optical supervisory channel (OSC) processing units for processing OSC signals contained in a wavelength division multiplexing (WDM) signal received from a WDM network and a switching unit for performing the path control of synchronous digital hierarchy (SDH) frames. An OSC processing unit transmits the SDH frame, containing wavelength information indicated by, to the switching unit. Another OSC processing unit acquires the SDH frame, containing wavelength information, from the switching unit and sets an OSC signal which is to be appended to the WDM signal to be transmitted, based on the wavelength information.

Abstract: A machine and a winding process receiving a continuous flow of flat and flexible elements (10) aligned along a longitudinal axis and partially overlapping, to form a spool (6) by rolling these elements into a spiral around a drum (8), with insertion between the turns of a flexible central strip (26), one end of which is fixed onto the drum and the other end of which unwinds from a hub (60) on which the strip has previously been wound, characterized in that the machine also includes a motor-driven resource (54) to regulate the transverse position of the hub (60) so as to perform lateral movement in relation to the spool (6) in order to maintain a constant alignment of the strip (26) during the winding process.

Abstract: The step support (17) or plate support comprises a rear crossmember (22) and a front crossmember (24) which together form a plane (E3) for receiving the tread element (9). There are two outer step cheeks (20.1, 20.2), wherein one of the step cheeks (20.1) is arranged on the right and one of the step cheeks (20.2) is arranged on the left, substantially perpendicular with respect to the crossmembers (22, 24). The two crossmembers (22, 24) are manufactured from deep-drawing sheet metal and are welded or joined or riveted or screwed or adhesively bonded or clinched to the step cheeks (20.1, 20.2) or plate cheeks to form a load-hearing frame. The height (H2) of the crossmembers (22, 24) at its ends is smaller than the height (H3) of the crossmembers (22, 24) in the center, with the result that the crossmembers (22, 24) have a curved shape.

Abstract: Disclosed are a photosensitive compound and a method of manufacturing the same. The photosensitive is composed of a naphthoquinonediazide sulfonic ester compound having at least one naphthoquinonediazide sulfoxy group, and having either at least one carboxy group with 1 to 8 carbon atoms or at least one alkoxy group with 1 to 8 carbon atoms, in one molecule.

Abstract: A quadrature amplitude modulator is provided. An oscillator generates an in-phase carrier signal having a rectangular wave, a trapezoidal wave or a waveform similar to these, and a quadrature carrier signal, the phase of which is shifted by ¼ cycle relative to the in-phase carrier signal. A multi-level driver generates an in-phase modulated signal by amplitude modulating the in-phase carrier signal with an analog in-phase baseband signal having a discrete voltage level or current level in accordance with the in-phase baseband data. Likewise, the multi-level driver generates a quadrature modulated signal by amplitude modulating the quadrature carrier signal with an analog quadrature baseband signal having a discrete voltage level or current level in accordance with the quadrature baseband data The multi-level driver generates a modulated signal, the amplitude of which takes a discrete level, by combining the modulated signals together.

Abstract: A technology enabling a base station to transmit acknowledgement (ACK)/negative ACK (NACK) information about data received from a terminal is provided. A cyclic shift value difference of each terminal may be maximized and a radio resource for transmitting the ACK/NACK information may be assigned without collision.

Abstract: A well tubing valve including a substantially tubular body connected in a tubular string and a rotational valve member having at least one aperture. The valve member is a sleeve having a part spherical surface, is rotationally moveable relative to the body to align and misalign the at least one aperture in the valve member with a port in the body. The valve member is actuable to rotate relative to the body in a single direction, and moves from the open position to a closed position and back by rotation in the same sense. The valve also includes a sealing arrangement adapted to provide a metal seal that is biased to seal against the part spherical surface.

Abstract: An apparatus and method for estimating scale ratio and noise strength of an encoded image includes an edge detection unit, a projection histogram calculation unit, a distance histogram calculation unit, a scale ratio estimation unit, a block boundary determination unit, and a noise strength estimation unit. Compressed noise, such as a block effect, included in an image can be efficiently reduced without prior information about the image.

Abstract: An equalizer circuit receives digital amplitude data A[N] which represents the amplitude level of the N-th (N is a nonnegative integer) signal to be transmitted via a transmission line and timing data T[N] which represents the cycle of the signal, and performs waveform shaping. The equalizer circuit includes: M (M is an integer) calculation units ECU1 through ECUm; and an adder ADD1 which adds the output data of the M calculation units ECU1 through ECUM and the amplitude data A[N] together so as to generate equalized amplitude data D[N]. A step response waveform RSTEP(t) for the transmission line is approximated by Expression RSTEP(t)=SSTEP(t)·(1?Sj=1:M fj(t)) using M (M is an integer of 2 or more) functions fj(t) (1?j?M) and a step waveform SSTEP(t) with the time t as an argument. The representative value of the function fj(t) in a range between T1 and T2 is represented by a function gj(T1, T2).
